A method and apparatus for forming a beverage involves the use of a filter aid, e.g., that is provided in a beverage cartridge with a beverage medium in a dry state. In one embodiment, a cartridge including a dried fruit material may also include a filter aid, such as perlite, diatomaceous earth or cellulose, that is mixed together with the fruit material.
